Wow.
Oddly enough the plot of this claymation is actually better than every other claymation I've seen on newgrounds thus far. Perhaps you rise to the top of the clay pile...
I would work on editing. I've noticed that the number one trend in all the claymation videos on NG is a severe lag in dialogue. The conversations just tend to drag out far too long (ex: your character finally announcing he's in the cannon).
If you made that time a bit faster/more natural then you'd really have an edge over all the other videos...as it would be coupled with your transcendant plot lines...
